The benefits of fish oil extend beyond heart health. A now famous Harvard study (conducted by Andrew Stoll in 1999) concluded that individuals who regularly experienced certain mood irregularities typically exhibit low levels of EPA and DHA. During this double-blind, placebo-controlled study, nearly 75% of the subjects treated with Omega-3 experienced relief from their symptoms. According to Dr. Stoll, "Our study results indicate that fish oil does possess the elements needed to maintain positive mood."*

Omega-3 may also be beneficial for stiff joints, inflammation, and occasional aches. Within the body, DHA and EPA compounds are converted into powerful agents known as prostaglandins. These prostaglandins are substances that the body produces to help manage inflammatory response; thus offering effects related to the body's management of mobility, pain and various forms of physical stress.* source is Now University.
